Hi VanillaGT, and welcome to Mageia.
I would suggest a re-install.
choices for you, I cannot know your use case.:
1/ Re-use the existing partitions :/boot/EFI, / and /swap. (same as my lenovo n23 ex-chromebook, 32GB eMMC). then use the Sandisk 64GB card as a data disk, and be sure to
store all your personal files there. your "home" directory, as part of /, will store things like your browser passwords, configuration files for applications... etc.
2/ Re-install, but this time use "Custom Disk Partitioning". Re-use the existing partitions, but this time mount/add the Sandisk 64GB card (sdb) as your /home.
continue as you did last time.
*Note: the Sandisk 64GB card must never be removed. It will contain all your user data files, and configuration files. It also has a UUID (A UUID (Universal Unique Identifier) is a 128-bit value used to uniquely identify an object). The system looks for this UUID when booting, and it will likely prevent booting if it is removed.
Enjoy using Mageia.
